MailOnline has contacted Katie's representatives for comment.

Their marriage has come under strain due to 'sex addict' Kieran's infidelity struggles, and in August Katie claimed she was divorcing the former stripper after discovering he embarked on a lengthy affair with the family nanny Nikki Brown.

However Nikki, 40, later came forward to deny the accusations, and claim Katie simply wanted to place blame on someone else for the split.

Kieran has since spoken to The Sun about his troubles, confessing he was a sex addict who needed professional help.

The father-of-two, who married Katie in 2013, admitted: 'This wasn't a big love affair... I'm a sex addict and needed a thrill.'

Despite claiming she would be leaving him, the couple still live together, and in December, Katie admitted that she still 'loved' her husband.

She told Reveal: 'I still love him. The Kieran that I know, I love. The other Kieran [who cheats] is horrible. It's just so far away from the man I married.

'I can't believe he slept with those women. It proves he has an addiction. I know it's not me. He has an addiction because those women are disgusting.'

Kieran was also hit by cheating allegations at the beginning of their romance, with Katie catching Kieran kissing her married ex-best friend Jane Poutney, 49, while on holiday in Cape Verde in May 2014.

Katie and Jane had known each other for 20 years when the ten-month affair came to light, and the latter was even maid of honour at Katie's weddings to Alex Reid and Kieran.

While Kieran paid tribute to their anniversary on social media, Katie instead documented her latest non-surgical bum lift for fans.

The mother-of-five flaunted her peachy posterior in a skimpy hot pink thong for the procedure - which is designed to deliver non-invasive fat removal and lymphatic drainage.
